well first off what's the shape?

hockeychick23 · Answer

I think it's C. mound shaped and approximately symmetric

inkyvoyd · Answer

what makes you think it's mound shaped?

hockeychick23 · Answer

well i just thought it was symmetrical and didn't think it was uniform so that would just leave the mound shaped answer to be symmetrical

inkyvoyd · Answer

well the difference between mound shaped and uniform is how the tails of the distribution look. AFAIK, the tails look about as tall as the middle in this distribution, which shows that it's actually not mound shaped

hockeychick23 · Answer

ohhh ok, am i wrong about it being symmetrical then? because if it were symmetrical then it would have to be approximately uniform (D)

inkyvoyd · Answer

Well, let's look at it this way. A mound shaped distribution and a uniform distribution are different in that there are more entries in the mean of a mound shaped distribution than in a uniform distribution

inkyvoyd · Answer

whether or not data are symmetrical really depends more on skew. Here is an example of asymmetrical but apprxoimately uniform data|dw:1424252836901:dw|

hockeychick23 · Answer

oh ok, so does that mean its uniform?

inkyvoyd · Answer
